Breeding objective

Breeding Objectives keep us focused on what is important to our ram buyers production system as well as the key profit drivers for their first cross ewe clients.

At New Armatree we have a SMART Breeding Objective:

S - Specific

M - Measureable

A - Attainable

R - Relevant

T - Time bound

This allows us to focus our selection decisions to be breeding the sheep that you need tomorrow, today.


At New Armatree we are continually reviewing and revising our breeding objective as we meet our targets to ensure that we are striving for continual genetic gain.


Our breeding objective is expressed in ASBV (Australian Sheep Breeding Value) units to ensure what we are actually improving the genetics of our flock.

Index Target

BLX Index Breeding Objective:

To continue to improve the BLX index at a faster rate than industry.
